Watering a flower garden at a city park
I've been told to water a flowering garden at a city park by aiming the city water out of a garden hose at the roots of the plants. Before, I was using the garden hose with city water and watering on top of the plants. Someone from the committee for volunteers for this park said that makes the leaves turn brown by watering on the leaves (top down) instead of the roots, especially when the sun comes out. The example that was pointed out to me was a daisy plant, where the leaves were turning brown. These plants do get rain on them, but basically someone has to physically water them every so often. No one gets paid. What's the correct way or does it matter?
